TRACTION-WHEEL LUG. 1

Application filed May 26,

The present invention is directed to a novel and simplified constructionof a traction wheel lug, and particularly the manner in which the sameis attached to a traction wheel of the narrow rim type. 1

A further object of the invention is to provide a novel form of tractionwheel lug in combination with a narrow rim traction wheel in which thefastening means in the form of a bolt, extends in a radial directionwith respect to the wheel, within a bracket riveted to one side of therim.

These and other objects are accomplished by providing a construction andan arrangement of the various parts in the manner hereinafter described,and particularly pointed out in the appended claims.

Referring to the drawings, Fig. 1 is a side elevational viewofafragmentary portion of a narrow rim traction wheel showing my improvedform of lug mounted thereon, and means for securing it to the rim.

Fig. 2 is a cross sectional view taken on the lines 2-2 of Fig. 1, and

Fig. 3 is a top plan view of the lug shown in Fig. 1.

The lug illustrated and described'in the present instance is adapted foruse in connection with the form of traction wheel illustrated anddescribed in my co-pending application Serial No. 269,193, filed April11th, 1928.

In illustrating one form of my invention, I have shown the same inconnection with the narrow rim traction wheel, a frag- 'mentary portionof which is shown in Fig.

1 and generally indicated by the reference character 10. This narrow rimmember is preferably made of a flat piece of steel. with the narrow edgethereof forming the outer periphery of the wheel, and the relativelywide surface thereof, as indicated at 11 extending parallel with thelines forming the radii of the wheel. The lug proper, generallyindicated by the reference character 12 comprises a hollow form of lughaving inclined surfaces 13 and 14, which converge to an apex indicatedat 15. Extendin longitudinally through the body portion 0 the lug is asubstantially triangular opening 16 forming a 1928. Serial No. 280,727.

base or bottomportion as indicated at 17. it

.Extending through the base or bottom portion 17 of the lug is asquareopening 18 locatedto one side of the medialcenter of the lug,through which the head of the fastening bolt, hereinafter described,maybe inserted. Located on one side of the square aperture 18 andcommunicating therewith soas to '00- cupy a position substantially inthe center of the lug, is'an elongated semicircular aperture or recess19,through which the shank of the bolt extends. Secured to. oneside ofthe rim 10'of the wheel by means of rivets .20 is'a bracket 21, whichhasits center portion thereof, as indicated at 22, ofiset or raisedtoem. brace. the bolt, or in other words, so as "to form". an aperture 23between the bracket :21 of the rim 10 of the wheel. The bracket 21 is ofsubstantially the same widthas the rim 10. Projecting inwardly from thebase-l7 of the lug 12, and preferably adjacent one sidethereof,;- aretwo projections, 24 which are adapted to: engage one side of the rim forpreventing the lug from turning onthe bolt. After the bracket 21' hasbeen secured to the rim by means of the rivet 20, the'head 25 of thebolt 26 is inserted inthe square aper= ture 18 in the base 17. of thelug12, and adjusted so that the body portion of the bolt is set'into theelongated semi-circular slot 19, after which the bolt is inserted in theopening or recess .23, of, the bracket and the nut 27 y is then securedto the threaded. end of the number of these brackets may be'secured tothe side'ofthe rim. at.the propergspaced-intervals, sothat any requirednumber of these lugs may'be mounted on. the rim.

. From the above description it Win. a seen that I have not onlyprovided a very simple and efficient construction of a traction wheellug, but 2180, 3,, novel means of securing the same" to a narrow rimtractioniwheel, which permits readily attachment-to or detachment fromthe rim.

While in the above specification I have describedrone embodiment whichmy invention "may assume in practice, it will, of course, be understoodthat the same is capable of modification, and that modification may bemade 'Without departing from the spirit i-andascope of theinventionasexpressed in the following claims;
